LOUIS S. BURBANK, OF LUDLOW, MASSACHUSETTS, ASSIGNOR T LUDLOW MANUFAC TURING ASSOCIATES.-

AUTOMATIC FILLING-CHANGING 1100M.-

Specification of Letters Patent.

Patented Feb. 18 1919 To all whom it may concern:

Be it known that 1, Lotus S. BURBANK, a citizen of the United States, and a resident of Ludlow, in the county of Hampden and State of Massachusetts, have invented an Improvement in Automatic Filling-Changing Looms, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to looms and particularly to automatic filling changing looms, and more especially to automatic filling changing looms of that type wherein the exhausted or substantially exhausted filling is replenished by replacing the running shut tle with a new shuttle.

In order that the principle of the invention may readily be understood, 1 have dis closed a single embodiment thereof in the accompanying drawings wherein:

The loom of my invention and one term or", which is herein disclosed may be used in various relations and for .Weaving various kinds of material. It is, however, so far as the disclosed embodiment is concerned, particularly adapted for Weaving jute and other coarse and heavy fibers in the manufacture of gunny bagging.

ln carrying out my invention the filling may be replenished in any suitable manner, but preferably by replacing the exhausted or substantially exhausted shuttle with a refilled shuttle. The filling supply may be in any suitable form or package, but in that type of loom to Which l have particularly applied my invention the filling supply is in the form or" a loobbinless cop or package of yarn coiled into a generally cylindrical mass having nested conical layers and having pref rably more or less tapered ends and forced usually with considerable pressure into theshuttlc, .vvhich may be and usually is of large size, the construction being such that the fillhig package tightly fits in the cavity of the shuttle throughout the ent re length of such package, and cannot be displaced in the operation of the mechanism even when the portion of the filling package remaining in the shuttle is extremely small, and the shuttle has become substan tially exhausted.

ln an ordinary loom there is a briei time in the lay stroke when both boxes may be emptied of the shuttle and still not interfere with the picking or dagger actions of the loom. and the loom Will run on uninterruptw edly if the shuttle be restored to its original "place at or before the expiration of such time. The limits of the period referred to are the passing oi the frogs by the daggers on the forward stroke 01 the lay and the beginning the picking action on the fol leaving back stroke of the lay.

T motion be suspended for pick, or 11 were no no mung Zfi'OtlOli on the mpty shuttle be d scharf d z: the re";

and a refilled shuttle may be inserted in the opposite box. Such refilled shuttle may be put into the opposite box by sending it into the shed or Without passing it through the shed provided the action of the filling motion be suspended temporarily and the takeup motion be similarly suspended.

The disclosed embodiment of my invention is based upon such general principle or operation and the removal of the empty shuttle and the entry of the refilled shuttle preferably take place during the period referred to, although it is clearly to be understood that my invention is not limited to such timing or arrangement of the parts. Although I have shown my invention as applied to a shuttle having a bobbinless cop or package, it is to be understood that my invention is in no Wise limited thereto.

In a previous application filed by me I have disclosed means whereby the spare shuttle is supported at one side of the 100m and in the replenishing operation is picked across the loom into the opposite box. the exhausted shuttle being discharged from the 100m at the same side thereof jYllE-IQ the spare shuttle is supported. In the disclosed embodiment of the present invention, the spare shuttle is supported at one side of the loom and in the replenishing operation is picked across the loom into the opposite i301,

and the exhausted shuttle is picked from the shuttle box at the spare shuttle side of the loom across the loom into a receiver or re ceptacle .Which is at the same side of the loom as the shuttle box into which the spare shuttle is picked in the replenishing operation.

Referring more particularly to the drawings, the sides of the loom are represented at 1, the breast beamat '2, the loom arch at 3, the lay at l. the lay swords at 5, the rocker she at 6, the shipper at '7, the bottom girt of the loom at 8 and the hand rail at 9.

These parts may be of any suitable construction.

Power may be applied to the loom in any suitable manner and preferably by means or a driving pulley 10, shown most clearly in rigs. 2 and 3 and having fast and loose pulley members. Said driving pulley 10 is non a drive shaft ll, having thereon a iriving pinion l2, meshing With a gear 13, upon the cam shaft 1 Said gear 13 meshes with a gear 15 upon the crank shaft 16. The cranks of said are connected in the u ual manner by the sweeps 17 to the bracket lo at the oi the lay, as most clearly shown in Fig. 3. These parts may be of the usual construction.

Preferably 1 effect replenishment, as previously stated, by dischargingthe substantia y exhausted shuttle and by introducing v or replenishing shuttle. F or that pur- I have herein represented a support generally indicated at 19, for the spare shuttle or shuttles, and in this form f my invention I have represented two spare shuttles 20 and 21, in vertical alinement, and so arranged that the upper shuttle 21 may drop into place as soon as the lower spare shuttle 20 is picked from its support. As most clearly indicated in Fig. 2, the spare or replenishing shuttle box is supported in a horizontal plane but at an incline to the face of the reed M71161]. the latter is in a vertical position. The said spare shuttle box 19 is sup ported by means of a bracket 22, which as shown most clearly in Fig. 16 is supported from the breast beam and loom side. The said spare shuttle box has a bottom 23, bolted to the bracket 22, sides 24L and two members 25 and 26 constituting a cover.

Preferably I provide means for effecting adjustment of the spare shuttle box 19 so that it may be brought into correct alinement. For this purpose I have represented on the bottom 23 of the spare shuttle box 19 a pivot pin 26, upon which it may be turned in a horizontal plane. To permit such movement the bolts 26" extend to suitable elongated slots in the said bottom 23 and may be tightened in any position of adjustment of said box 19.

The uppermost spare shuttle 21'is supported at its rear end or tip by a small bracket or member 27 secured by bolt 28 to the cover member 26,'and having a vertical slot 29 extending part way through said member or bracket 27 and wherein is received the tip 30 of the said spare shuttle 21.

The said bracket or member 27 is preferably formed with a downwardly inclined or slanting part 27 along and from which the tip of the shuttle will slide when the opposite tip of the shuttle is no longer supported. The opposite tip 31 of the shuttle is frictionally supported in a bracket or member 32 secured by bolt 33 to the cover member 25, and having a Vertical slot 34: extending entirely therethrough. The bracket or member 82 merely positions the forward end of the shuttle 31 and said shuttle rests by gravity upon the underneath spare shuttle 20 or rather upon the spring tongue or strip 35, which confines the filling package in place. When the lowermost spa-re shuttle 20 is picked from the spare box 19, the uppermost spare shuttle 21 drops into the place vacated by the spare shuttle 20 and another spare shuttle is placed by hand thereon. Each spare shuttle in turn is picked from the spare box 19 by the supplemental picker arm 36, hereinafter more fully described, and

having a picker 37, which during its inward sweep temporarily supports the inner end of the spare shuttle 21 and until said spare shuttle 21 is permitted to drop in a proper manner into the place of the shuttle 20 and with the tip end 31 slightly preceding in movement the tip end 30. The members 27, 32 are so spaced as normally to prevent the rear end of the shuttle from sliding off the slanting part 27. The upper shuttle 21 is supported during inaction by the lowermost shuttle 20, and during the transfer action by the top of the outgoing shuttle 20, and immediatelythereafter by the picker 37 which is of the same height as the shuttle, so that the forward end of the supported shuttle cannot descend below its guides at either end until after the picker has partially recovered. When the said shuttle 21 dips down at its forward end and when the picker 37 has fully recovered, the rear end of the said shuttle slides downonto the bottom 23 of the battery box ready for the next transfer.

I have represented at 38 in Fig. 19 a typical shuttle preferably employed by me with the loom of my invention, and having therein a cavity extending substantially the entire length of the shuttle and] containing no skewer. The filling package 39, preferably employed by me, is wound in any suitablemanner, but preferably in the form of nested cones. As diagrammatically indicated in Fig. 19, the said filling package 39 closely fits throughout its entire length the cavity of the shuttle and the yarn or filling is withdrawn in the weaving operation from the inside of the package as indicated at 40. The filling is preferably of a coarse character, such as jute, and the package is usually forced with considerable pressure into the cavity of the shuttleso that it fits tightly and with very considerable friction therein. Thus, as the filling is. withdrawn from the shuttle, the constantly diminishing portion of the package is firmly and frictionally held therein down to and past the time when and at the point at which the feeler indicates replenishment. The shuttle is provided with a horizontal slot 41 for the entry of the feeler.

Thefilling package feeler is most clearly shown in Figs. 6 to 11 inclusive. Therein I have represented the shuttle at 38 as positioned in the shuttle box having a front wall 4.2 and a back wall 43, the latter having an opening for the binder 14 functioning in the 1 5 usual manner.

The bracket 22 shown most clearly in Figs. 16 and 17, has bolted and adjustably secured to the under side thereof the feeler bracket 45, as shown most clearly in Figs. 8 and 9. Said bracket 45 has an upstanding portion 46, to which is secured the feeler casing 47, which in cross section is of the general form shown in Fig. 11. It has opposite spaced side walls 48 and 49, connected by a top portion 50. In said side walls 48 and 49 are longitudinal grooves 51 and 52, wherein is slidingly positioned the outer or shuttle feeling member or slide 53 of the feeler. The said slide 53 is normally inwardly pressed by two coil springs 54- attached thereto and also to the ieeler casing 50. When-the shuttle is in its box at the replenishing side of the loom, said shuttle feeler slide 53 contacts therewith as indicated most clearly in Fig. 9. The said shuttle feeler slide 53 is upwardly notched as in dicated at 55 in Fig. 9, so that when said slide 53 is positioned as shown in Figs. 9 and 10, a pawl-like member 56 is permitted to enter the same, being inwardly pressed by spring 57. Said pawl-like member 56 is pivoted at 58 upon an arm 59, fast upon a short shaft 60, so that when the member 56 is per-- mitted fully to enter the notch 55, the shaft 60 receives a movement of partial rotation. The arm 59 has rigid therewith the depending wing-like portions 61, havingadjustable screws 62, serving accurat ly to position the arm 59 upon the shalt 60, said arm being removable therefrom but secured thereto by a set screw 63.

The shuttle teeler slide 53 has opposite longitudinal grooves or ways 6% therein, receiving the filling feeler 65, which is of generally platelike form, and is herein shown as having an uptured outer end 66, to which is connected a coiled spring 6?, the inner end of which is connected by pin 68 to the shuttle feeler slide 53, so that said fillingteeler is constantly inwardly pressed by said spring 6?, and feels for the receding edge 69 or" the package. it or near its outer end the said slide has an opening 70 therein, which when the slide '65 moves inward past the receding edge of the package, registers substantially with the notch 55 in the shuttle teeler slide 58, thus permitting the arm as to move from the position indicated in 9 to the indicating or functioning position shown in Fig. 10, whereby through the connections hereinafter described the'replenishment is effected.

previously stated, the filling feeler slide 65 constantly feels for the receding edge 69 of the package. it is not until the filling has become substantially exhausted that the said slide 65 enters the shuttle or at least to more than a very limited extent. the contrary, the said 'ieeler slide 65 merely contacts with the outer surface oi the package, which is of the full diameter, and it is not until suflicie'nt yarn or filling has been drawn from the interior of the package that the receding edge 69 passes beyond the slide 65 so as to permit the latter to move in. The feeler slide 65 is, as stated, inwardly spring pressed and hence the said ieeler will move inwardly and will function when the force of: the spring 67 overcomes the resistance afiorded by the filling. lt is therefore evident that the ieeler slide 65 may force its way inward through coil or two oi the receding edge and berore the receding edge has wholly passed such slide, this dependmo .upon the strength or adjustment of the spring 67.

Any suitable means may be provided to efiect return movement of the feeler slide 65 into the feeler slide casing 47 and the outer slide 53. Herein for that purpose I have represented the said slide 65 as having its outer end beveled as indicated at 65' in Fig. 6, so that such beveled end may be engagged by the similarly beveled end 65 of the slot ll of the shuttle on the outward movement of the latter. The said slide 65 is then locked by the pawl like member 56 which has now returned to its former position.

Preferably l provide means whereby the operator is warned before replenishment occurs, since the shuttles are picked across the loom with great rapidity and force. For this purpose I have mounted upon or adjacent to the feeler casing 4-7, a bell 7 0, against which strikes a clapper 71, supported upon a spring arm 72, secured to a bracket 7 3-, be-

low or adjacent to theshaft '60. The said spring-arm 72 is adapted to be flexed by one of the lugs or pins 74, upon the outer end of the shaft 60, and when said spring arm 72 is released the bell is struck.

Any suitable means maybe provided to efiect replenishment upon the indicating movement of the filling package teeler. l shall describe in detail that form of means and those connections constituting one em bodiment of my invention, without, how ever, limiting myself thereto.

The shaft 60, as shown most clearly in Fig". 2 has fast to the outer end thereof an arm it, which in turn is fast with a vertically positioned rod 76, as shown most clearly in Fig. 13, and which, end, enters the cycle box indicated generally at 77. The said box 77 is secured to the front girt oi: the loom, and comprises the outer cover-like metallic member 78, and the inner casthip,- 79, having a bearing wherein is supported a stud shaft 80, receiving thereon for step-by-step rotary movement a cam 81, having "formed therewith or secured thereto a ratchet 82, having teeth 88, one of which, as shown most clearly in Fig-13, is more widely spaced than the others, said cam and ratchet having a hand knob 83' for turning the same.- l fith the teeth of the said ratchet S2 is adapted to engage the end 84 of a pawl 85, which is pivotally connected at 86 to an arm 87, last upon the rocker shaft 6 of the loom. During the normal operation of the loom, the end 84: of the pawl 85 merely slides back and forth along the elongated portion 88 of the ratchet without effecting any turning movement thereof. When, however, the filling package feeler functions, the rod 76 is moved axially upward, and through the connections, of which one form is shown, the n at its lower 1,294.,e7a s ratchet 82 receives a slight turning movement sutiicient to bring it into such position that the pawl 85 may now turn the same.

For the purpose I have herein represented the axially movable rod 76 as having its lower end connected at 89 to the arm 90 of a lever pivoted at 91 in the wall of the cycle box and having an outer weighted arm 92. The inner end of the arm 90 is provided with a head 93 that takes under and supports a pawl-like slide or arm 9%, herein shown as formed in two parts, and pivoted at 95 to the arm 87. When the rod 76 is moved axially upward by the indicating movement of the filling package feeler, the slide 91 is lifted through the agency of the lever arm 90. so that said slide 94, which normally is below the teeth of the ratchet 82, is lifted into line with the lowermost of said teeth and in the neXt movement of said slide 1 to the left viewing Fig. 13, the ratchet 82 is thereby turned slightly in a clockwise direction viewing Fig. 13. so as to bring a tooth of the ratchet within the range of movement of the pawl 85. The said ratchet 82 is then sufiiciently turned to cause the high part 96 of the cam 81 to engage a lug or projection 97 upon a lever arm 98., which is pivoted upon a shaft 98' in the cycle box and at its lower end is pivotally connected at 99 to a bracket Or sleeve-like member 100. fast upon a slide rod 101. The upper end of hand lever 98 has attached thereto a coil spring 102 that is connected at its other end to a holding pawl 103 for the ratchet 82. The holding pawl 103 is pivoted at 104 and at the same point is pivoted a brakelever 105, adapted to engage the brake disk 106 fast upon the said stud shaft 80, thereby preventing over-movement of said shaft. 7 The lower end of the brake lever is connected by a coil spring 106. to the end of the sliding rod 101.

From the foregoing description will be evident that through the described connections. the rod 101 will be moved axially upon indicating or functioning movement of the filling package feeler. The sa d rod 101 is operatively connected with picking means. whereby the exhausted or substantialiv exhausted shuttle will be picked across the loom into the discharge receptacle. and whereby the spare shuttle will be picked across the loom into the shuttle box.

it is of course evident that many features ofmy invention. as for example the conneci'ions for effecting repleni. nnent. may be employed. whatever he the character of the article that is supplied by the replenishing action. that is whether it be a shuttle or a filling package.

The axially movable rod 101 shown also in Figs. 20. 26 and 27. has fixedly secured near its opposite end a slee eor bracket 10?, which is pivotally connected with an arm 108, fast upon a vertically positioned rock shaft 109, shown most clearly in Fig. 20, as mounted in suitable bearings 110, 111 in upper and lower brackets 112, 113, secured to the side of the loom. Fast upon the said shaft 109 and near the upper end thereof, is a second arm 114, having a cam roll 115, rotatably mounted thereon. In order to prevent over-movement of the arm 1141 it is provided with a roll or projection 114 to take against the hub of the picker cam hereinafter referred to. When the filling package feeler functions, the rod 101 is moved to the left from its normal position shown in Fig. 26 into the position shown in Fig. 27, thereby bringing the cam roll 115 into the path of movement of a certain cam whereby other parts to be described are moved and the picking is efiected.

The cam shaft 14 has thereon the usual picker cams, one of which is indicated at 116 in Figs. 20. 21 and Said picker cam 116 is provided with means whereby when the filling package feeler functions, the re ular picker arm and the supplemental picker arm are specially moved so as to edited the throwing out of the substantially exhausted shuttle and the throwing in of the spare shuttle. For this purpose. 1' have provided the following mechanism.

llpon the illustrated picker cam 116 is pivotally mounted upon a. stud 117, a memher 119 having an irregular cam surface 119, and outer cam surfaces 120. 121. said latter surfaces being adapted to be brought respectively into the path of movement of the regular picker roll 122. and the supplemental picker roll 123 respectively, as shown most clearly in Fig. 22. In order to prevent over-movement the member 118 is provided with a lug 123 adapted to take between shoulders 1'23 upon the periphery of the picker cam 110.

The roll 115 upon the lever arm 114 when moved into the functioning position shown in Fig. 27 is adapted to enter beneath the cam surface 119 and thereby to elevate the member 118 from the position shown in Fig. '21 to that shown in Fig. and thefeby to cause said cam surfaces 120. 121 to act upon the picker rolls 122. 123. Preferably 1 provide means to lock said member 118 in its outer or elevated position, and for the purpose. as herein represented. i have pivoted upon the stud 121. located upon the picker roll 118, a bell crank lever constituting a lock. the arm 125 of which has connected. thereto a coil spring 128 that is connected to the picker roll at 127, thereby tending constantly to move the lever into locking position. The other arm 128 of said lever has a locking portion 12 which takes under the member 118 when in its outer or elevated position and locks the same. The uinocking of said lock is effected by the continued mo tion of the roll 1:15, which the cam surface of said bell crank lever and restores the same to the position shown in Fig. 21. During the normal weaving operation the regular picker roll 122 is constantly acted upon by the picker cam 116, but the supplemental picker roll 123 is out of the plane of said picker 20011116, and is not acted upon thereby.

Upon a shaft 131, shown most clearly in Figs. 20, :26 and 27, are loosely mounted the regular picker arm 132, which efiects the picking of the running shuttle and the ejection of the substantially exhausted running shuttle from the loom, and the supplemental picker arm 133, which controls the picking of the spare shuttle from its box across the loom into the shuttle box at the opposite side of the loom. The regular picker arm 132 is provided with the pick roll and the supplemental picker arm is provided with the pick roll 123. Thus the regular and supplemental picker arms 132 and 133 are caused to be moved to effect the replenishing operation and it will be evident from the illustrated construction that the timing of parts is such that the substantially exhausted shuttle is picked "from its box into the exhaust receptacle very slightly after the picking of the spare shuttle from the spare receptacle into the opposite shuttle box of the loom. Fig. 2, 'it is evident that the paths of the substantially exhausted running shuttle while being ejected, and of the spare shuttle in being thrown into action, cross each other. Hence it is of the highest importance that the timing be such that the two shuttles do not touch each other. In practice the spare shuttle precedes the flight of the discarded shuttle by a small fraction of a secend, and both shuttles are in flight at the same time.

The regular picker stick 134, most clearly shown in 3, is acted upon in the regular manner during the'normal operation of the loom, but receives the described special movement to effect the ection of the spent shuttle. The supplemental picker stick is representedat 36 in Figs. 1 3 and elsewhere. It is pivoted at its lower end at 136 to a link 1137. itsel'l ivoted at 133 u on the framinitz U of the loo-m, and a coiled spring 138 connects said picker stick and a bracket upon the loom frame. At about mid-height said supplemental picker sticlr 38 has secure thereto a hraclret 139. to which is pivoted a 1&0 a supporting linl: 141. the upper end which is pivoted at M2 to the brat-hethe spare shuttle support. is'sueh said s is moved at C) L) He Heev i no cons tructi on Viewing.

The loom is provided with a take-up which may be. of any suitable construction and preferably 1 provide means to suspend the operation of said take-up during replenishment. F/hile for this purpose any suitable means may be provided, l have herein represented the following mechanism.

Referring to Figs. 3, l and 5, the take-up roll is indicated at 143 and the cloth roll at 14A. Said take-up roll 143 is provided with a ratchet formation 1&5, with the teeth whereof engages a pawl 1 16, pivoted at 1%? upon a lever 148, loosely mounted at 149, axially of the take-up roll, and having adjustably connected to its outer end at a link or rod 151, which as shown in l i 5 is pivotally connected at its opposite end at 152 to a bracket 153 upon the lay sword. lhus in the normal operation of the loom, the talieaip roll receives a regular step-bystep movement and preferably a holding pawl 15d is pivoted at 154 to prevent retrog ade movement of the take-up roll.

At 155 upon the frame l pivot alever 155 having thereon a pin 155", which is adapted to engage and to throw out of action at suitable times the holding pawl 15%. The said lever 155 is provided with a dependingarm 155' having a stop or projection 155" adapted to be engaged by the weavers foot and swung in a clockwise direction, viewing Fig. l, thereby lifting the pawl 15% out of engagement with the teeth of the ratchet wheel 145. A spring 155 is preferably employed to return said lever 155' to inactive position.

ln order to suspend the action of the take-up roll during the replenishing operation, I have herein represented the shaft 98 as having secured thereto a downwardly eidending arm 156, shown in dotted line on Fig. 13 and which at its lower end is pivotally connected to a rod 157. which at its outer end is pivotally connected at 158 to a lever arm 15%), which is adjustahly connected at 160, 161 to the main lever arm 162, fast upon a reel: shaft 163, which also has secured thereto an inwardly extending and preferably adjustable arm 16%. which extends into the path of movement of a depending arm 165, last with the pawl 146. The construction and arrangement of parts are such that when replenishment is indicated the lever arm 18% is lifted when the upper end the lever 1&8 moves rearward or in contracloclrwise direction viewing Fig. l. the arm 1 85 of the pawl 143 strilres against said 18d and thus the pawl 1 23 is lifted so as to suspend the take-up action until said pawl 146 is permitted to drop.

"Pre erably I provide means wherehy the take-up let may manually be thrown I to permit the turning back 1 any purpose. For

' are represented Lin pawl H6 as'having thereon a projection 166 and upon the holding pawl 154 is pivoted at 167 a pawl-like member or dog 168, which when turned into upright position rides under the projection 166 and thus lifts and holds the pawl 146 from engage ment with the teeth of the ratchet 145.

The lay of the loom is provided with a suitable latch, not herein shown, for the purpose for holding the daggers up out of operative position whenever desired. Such latch and the described pawl-like member or dog lob are provided, so that the loom may. when desired. be turned over by hand; that is to say, by throwing into action such latch. the shuttle may be removed, thus stopping the weaving and by throwing in the dog. the take-up is stopped. The cloth can thus be held stationary under its normal tension and the loom turned freely forward or backward for any emergency.

Any suitable means may be provided to receive the spent shuttle when it is picked across the loom as a part of the replenishing action. Preferably for the purpose 1 provide a receptacle which is carried by the lay of the loom at the. side thereof opposite the spare shuttle support 19.

Herein and as most clearly shown in Figs. 1 and 28 to 33 inclusive, 1 have represented the lay as having secured to the front ther of at or near the end opposite the spare shuttle receptacle 19, a plurality of metal straps U39. preferably of the form shown in Figs. 30 and 31 and having secured to the down-turned ends 170 thcreot a preferably wooden strip 171.- Suitably spaced laterally from the wooden strip 171 is a curved or inclincd strip 172 shown most clearly in plan in Fig. 28 and against which the spent shuttle tip strikes said strip 172 has a bolt U3. which is adapted to be adjustably secured in a slot li t. whereby the said strip 172 may be positioned at the proper angle to receive the impact of the shuttle. Jointed to the inner end of the strip 1T2 by means of a pivot pin 175 is another strip 176. the other end of which is adjustably secured in position by means of a bolt 1T6 entering the slot 177 in one ot the strips .169. The said strip lit? is positioned in general parallelism to the strip 171. and is spaced sufficiently therefrom to receive between them the spent or discarded shuttle 178.

as a hollow member secured by bolts 182 to the arm 180 and having in its front wall a piston 183 in the recessed face of which is set a block of leather 184 or other suitable material to receive the impact of the shuttle. The piston is provided with a stem 185 which extends through a suitable opening 186 in the rear wall of the hunter 179. I may provide any suitable means for permitting a yielding but resisted movement of the piston. For the purpose I have represented the hunter as partially filled with small pieces 187, which are preferably metallic and may for example be rattling castings or shot, which become displaced and are forced upward by the piston movement due to the impact of the shuttle, and which force the piston outward again when the shuttle has been removed from between the said strips 171, 176. If desired, the return action of the piston may be supplemented by a coiled or other spring. The hunter 179 is provided with a screw cap 188 for permitting the insertion of the pieces 18?.

Preferably I provide means for removing the ejected shuttle fron'i its position between the strips N1 and ll'i'l into a box or receptacle from which it may be manually removed. F or that purpose I have represented the framing of the loom as havin secured thereto a casting 189, to which is secured by metal straps 190 or otherwise. a box or receptacle ltll.

The shuttle is discharged from the regular shuttle box at the right hand side of the lay viewing Fig. 2 while the lay is moving forward and while the shed is closing.

l fhile the lay is finishing its forward stroke. and beginning its backward stroke at the point where the shed is practically closed, the shuttle that is being discarded rides upon the warps constituting" the upper shade of the shed. and therefore passes somewhat diagonally or at a forward slant across the lay. and therefore in front of the regular shuttle box at the hand side of the lay and into the receiver formed by or including the spaced strips 171. H6. The shuttle then momentarily rests upon; the stationary plate 181. but in the continuous backward movement of the shuttle is wiped oi the plate 181. drops to the shelf below and is pushed tor-ward by the returning lay into the i031": from which it may be removed by hnd. spare shuttle at the same time is picked across the loom above the closing shed s 'htly in front of the ejected shuttle and at a faster :iipced.

'lhe inst or spare shuttle must have speed enough to box. that is to torn-e the binder open. and prcterablv it is thrown across the loom at shuttle speed. 'ihe ejec ed Shuttle is. h 2' own as easily and at as low a l as p uctica' I o a therebv lessen of: in or;-

der to free the outgoing or ejected shuttle from the lay boxes, 1 preferably utilize the retarding action of the lay followed by the reverse movement thereof. The outgoing or ejected shuttle is shot or picked straight for its opposite box by the regular picker stick, and if the lay were stationary, or if it were not moving at a uniform speed. it would box in the customary manner on the last half of the lay stroke. in accordance with my invention, however, the change of shuttle is made on the forward part of the lay stroke.

in the regular picking of an ordinary.

loom the shuttle is normally held against the reed by the retardation of the lay fol lowed by its reverse acceleration. Both of these forces act in the same direction, namely, backward, to hold the (lying shuttle against tie ree Thus, on the forward half of the lay movement in the disclosed embodiment of my invention, the reed present ing no obstruction, the shuttle is in effect swerved forward after leaving its box, thus missing the opposite box and entering the spent shuttle receptacle, certain forms of which are herein shown.

Actually the lay is swerved by the retardation thereof, but the effect of such movement of the lay is to deflect the shuttle as stated, so that it does not enter its regular box, but is received in the spent shuttle rccep acle. The shuttle transfer action is such in the disclosed embodiment of the invention. that the weft is omitted for one pick during the time of replenishment. Thus, on two shade goods the original which the detection was nmde will again open to receive the first piclz from the replenished weft. Furthermore the tahstop mechanism and the operative connections between the fee-lei and the replenishment mechanism and between the feeler and take-up Q stop mechanism are such the b s r oods, the said orig she c a ntion made will 'll be caused to susc two piclrs more or ea ers ln Figs. 3 35 and 36, l have represented still another form of spent shuttle receptacle and one which in many cases preferably employ. Therein the lay d has bolted thereto a casting or month 229 which is preferably metallic. Secured to the upper transfer portion of said casting or month 229 by bolts 230 is a flexible member 231 which is preferably a leather belt or strap. The said strap is bent into general loop form as indicated most clearly in Fig. 35, and its opposite end is secured by bolts 232 to the lower transverse portion of said casting or month 229. Suitably spaced from the casting or mouth 229 by more than the length of the shuttle is a support 233 preferably in the form of a metal bracket, which is not a complete rectangle, but has an upwardly extending rear memberor top transverse member and a downwardly extending end 23% terminating a considerable distance above the bottom of the bracket or month 229. The said belt or strap 231 is provided with slots to receive bolt-s 236 whereby the belt or strap is secured to the said support 233. To the downwardly extending end 23% of the support 233 and to the outer downwardly extending portion of the casting or mouth is secured a longitudinally extending strip 237 which is preferably of wood and is cut away intermediate its ends as represented at 238. The said strip 237 forms the front of the receiver chamber for the spare shuttle. but it extends only approximately half way down the same or about to the level of the warp, thus furnishing an opening at the bottom for the shuttle to be pushed through by the action of the lay and at the top forming the front of the chamber.

Laterally beyond the lower portion 239 of the belt or strap 23l is a shelf 2% of 1986i or other suitable material which is ad as wide the left hand picker stici-i c 'oi and the other lay parts will permit n which the said lower portion 233 o 23 rests and slides. The
